Public bug reported:
Hi,
Using python-ceilometer 1:8.1.2-0ubuntu1~cloud0 on Ubuntu 16.04.3 LTS,
we just got the traceback below. The problem is that a single libvirt
XML was missing the "nova:owner" block (I don't know why), and it looks
like this single problem was impacting meter collection for all the
other VMs. Once this VM got removed, the meters were properly populated
(see below for before and after the VM removal).
A single bad XML should not block collection for all the VMs.
Thanks
